How does Box No. VIII address unity of invention in the Written Opinion?
Box No. VIII in the Written Opinion of the International Searching Authority addresses the important concept of unity of invention in patent applications. According to MPEP 1845, “Box No. VIII is used to indicate a lack of unity of invention.”
Key aspects of Box No. VIII include:
- Identification of groups of inventions that lack unity
- Explanation of why the inventions are not considered to be a single general inventive concept
- Indication of which claims relate to each group of inventions
The MPEP states: “If a lack of unity of invention is found, the examiner must explain the reasons for this finding and indicate the groups of inventions.” This means that the examiner must provide a clear rationale for why the application contains multiple inventions that do not form a single inventive concept.
Understanding Box No. VIII is crucial for applicants because it may require them to limit their claims to a single invention or file multiple applications. It also provides guidance on how to potentially argue for unity of invention or how to proceed with divisional applications if necessary.
The concept of unity of invention is further elaborated in PCT Rule 13, which states that “The international application shall relate to one invention only or to a group of inventions so linked as to form a single general inventive concept.”
